Clinical parameters of the studied subjects

Parameter	ULD CT-Pure IR	PRSS	p-value
Demonstration of exact shunt entry point to peritoneum/pleura/atrium	22/22 (100%)	Not testable	-
Clear demonstration of shunt tip	22/22 (100%)	21/22 (95.5%)	p > 0.009
Precise identification of anatomic location of shunt tip	22/22 (100%)	Not testable	-
Visualisation of entire imaged shunt course	22/22 (100%)	8/22 (36.4%)	p < 0.001
Demonstration of shunt complications	Not testable *	Not testable *	-

PRSS and ULD CT-Pure IR images were compared using a binary scale (1, yes; 2, no) for the included parameters. Contingency squares were generated for each variable, and Fisher’s exact test was performed. A p-value < 0.05 was considered statistically significant

*There were no shunt-related complications in this study
